The JBoss Group is to discontinue its JBossTwo event which runs the same time as Sun Microsystems' JavaOne developer show.
In the past, The JBoss Group publicly battled with Sun over whether it should have to pay to certify its JBoss application server, which is released under an open-source licence, as compliant with Sun's J2EE (Java 2 Enterprise Edition) specifications.
In November, JBoss and Sun settled their differences and JBoss has taken its first steps toward J2EE certification.
Since then, the company has been working within Sun's Java Community Process (JCP) to develop a version of the Enterprise JavaBeans (EJB) specification, said Bob Bickel, vice-president of strategy and corporate development with JBoss.
"We have helped influence JCP standards in the past, but we officially joined the JCP in September, then we signed the J2EE certification agreement with Sun in November, and we joined this EJB group a couple of months ago," he said.
Sun, along with Java suppliers such as IBM and BEA Systems, are working on a new version of the specification that will be easier to use, and JBoss is contributing "significant resources" to that effort, Bickel said.
Because of its animosity towards Sun, JBoss did not even consider participating in previous JavaOne shows. The fact that this year it will not only be present in a booth, but also participate in the show's technical sessions, is indicative of a thaw in relations between the two companies, Bickel said.
